Abstract: A vertical type light emitting diode includes a nitride semiconductor having a p-n conjunction structure with a transparent material layer formed on a p type clad layer, the transparent material layer having a refractive index different from that of the p type clad layer and having a pattern structure of mesh, punched plate, or one-dimensional grid form, etc. A reflective metal electrode layer is formed on the transparent material layer as a p-electrode. A stereoscopic pattern is formed in the transparent material layer and the p-electrode deposited, and thereby forming the pattern in the p-electrode. Depositing the p-electrode on only 10 to 70% of the upper portion of the p type clad layer in an ultraviolet ray light emitting diode such that an area where the p type clad layer is exposed is wide increases the transmittance of ultraviolet rays through an area where the p-electrode is not deposited.

Abstract: Backlit video display systems where the backlights (for example, LED backlights) are controlled based at least in part on the content of the video signal of the video that is being displayed by the backlit video display system. The system can provide specific control of the three primary colors (for example, red, green and blue LEDs). The system can provide content-based control in a spatial mode. The system is a smart backlighting system with content-based controls at the following levels: (i) spectral, (ii) spatial, and (iii) temporal control. Also, some embodiments may provide a novel way of providing a backlit video display system with night vision (NV) capability through a unique four LED chip architecture.

Abstract: The use of the electride form of 12CaO-7Al2O3, or C12A7, as a low work function electron emitter in a hollow cathode discharge apparatus is described. No heater is required to initiate operation of the present cathode, as is necessary for traditional hollow cathode devices. Because C12A7 has a fully oxidized lattice structure, exposure to oxygen does not degrade the electride. The electride was surrounded by a graphite liner since it was found that the C12A7 electride converts to it's eutectic (CA+C3A) form when heated (through natural hollow cathode operation) in a metal tube.

Abstract: A mechanism and method for motion conversion is disclosed. This mechanism can be easily fabricated using standard bulk micromachining technology. Based on this method with appropriate design, a horizontal, in-plane motion can be converted to a vertical or angular displacement out-of-plane. This design has great advantages in micro devices, which are built from a single layer, i.e. wafer fabrication, where an in-plane force is easy to implement, such as by the use of comb drive mechanisms, but an out-of-plane motion may be hard to achieve. The mechanism comprises a pair of beams of different heights, rigidly connected together at a number of points along their length, such that application of an in-plane force to the double beam structure results in out-of-plane motion of the double beam structure at points distant from the point of application of the force.
